Could someone tell me the dangers of using propane? What would blow me up if I do it wrong? The seal is loose on my tank and leaking propane, now it's almost empty. Will have to switch tanks. I have an extra full tank. Anything I should know first? I just switched to using propane outside 2 weeks ago, not used to it. It's my 5th all grain batch. Tried phoning a friend but no one is answering. Just don't want to blow myself up.

Sounds like your on the right track and you are already getting that tank switched out. Definitely don't use the leaking one. As long as your connection is tight and your regulator is good, propane is really pretty safe. And of course make sure you always have good ventilation if you happen to be in your garage or something. You don't want CO poisoning.

Check for the washer between the fitting and tank. Make sure the tank is what is leaking, not the fitting or valve. Make sure it's nice and snug.

Try that back up tank and finish before going to store. With proper ventilation a small leak is not going to explode, but you really don't want the leak to catch fire as it is leaving the tank. That could cause a problem.

Don't use the leaking tank and don't store it inside if it is leaking. Return it or exchange it. Use the spare tank you have. If you can handle operating a gas stove you can handle brewing with propane, you just have to be mindful of the potential hazards like anything else.

Reminds me of an issue I had using my burner for the first time this past weekend. The flame kept getting sucked back into the venturi and then it would start burning at the connection between the gas line and venturi. Scared the crap out of me when it happened. I'm assuming it was due to the windy conditions. Is this dangerous, can the flame travel back up to the tank when this happens? Is there something I can do to correct this when it happens or do I need to shut off the gas and relight like I was doing?

Just going to put things on hold and switch tanks. Gotta run to the shop and get an adjustable wrench. Argh, was trying for a double brew day, back-to-back batches. Have never changed out a tank before, hubby hooked this one up for me so wish me luck. Thanks so much.
